Actually mythbuster disproved the whole survive a nuclear war thing. The initial blast is capable of killing any living organism it touches and cockroachs handle radiation poorly. Fruit flies and ants can both handle more radiation than a cockroach.

These little creatures are ridiculously tiny. I'm talking single-cell organism scale. Yet they can withstand environments so extreme, that they can actually survive out in space without any kind of life support. Oddly enough, they can actually be found pretty much anywhere, generally on leaves or in moss. Check http://sun [DOT] iwu [DOT] edu/~tardisdp/tardigrade_facts [DOT] html for more info.

actually they never said that i could survive and explosion. they said it could survive a nuclear FALLOUT. meaning it is resistant to radiation. if a nuke went off next to it it would die. no exeption. BRING ON THE RED!
